if I was the sort who made twinkle fingers, I'd do so (happily, I'm not). I think one of the most dangerous things that people do is reduce our enemies to some sort of boogymen. From this perspective (in the case of anarchists) cops, fascists, politicians, etc. are all absolutely evil, and we have nothing in common with them, ever, in any way. not even the same species as we (presumably elevated and superior?) anarchists. they are pigs, scum, and on and on.
Problem is, things aren't that simple. I 0once had a job that forced me to interact with cops. I was already an anarchist, I hated cops. I also realized through these interactions that there were people who are cops that are, in their own lives, kind, well-meaning humans (albeit, ones that made poor career choices, IMHO). But the problem was, they were also cops, and the nature of a job like that means that well-meaning kindness is subsumed to the role of cop, when the shit hits the fan. Insofar as there is no such thing as a good state, or good capitalism, there is also no such thing as a good cop. To the extent that good, well-meaning people continue to play the role of protecting and perpetuating what I seek to destroy, they continue to be my enemies.
This is a great example of why moralistic ideas like "good" and "bad" ought to be jettisoned from anarchist thinking. It is too reductive, and too based upon pre-existing (and often unexamined) frames of thought (which is why I am glad you mentioned Foucault!)
